Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a gas chromatograph having a pneumatic detector adapted to produce a component concentration measurement signal that is relatively unaffected by changes in carrier flow rate.  The detector includes an orifice connected in the flow stream at the output end of the chromato-graphic column to produce a pressure signal responsive to density.  This orifice signal also responds to flow rate of the fluid passing through the column.  A capillary is connected in series with the orifice to produce a second flow-responsive pressure signal which is subtracted from the orifice signal in a way to effectively eliminate changes in the final measurement output signal due to changes in flow rate while leaving the signal variations due to changes in density, i.e. concentration.  The orifice and capillary pressure signals are combined subtractively by means of a balanceable force-bar arrangement to which the pressure signals are applied by bellows of predetermined relative sizes, and which is automatically maintained in balanced condition by a rebalance bellows operated by a pneumatic nozzle-flapper feedback device producing the detector output signal.

Abstract: ABSTRACT OF THE DISCLOSURE An electrical insulator of the umbrella type comprising an insulating supporting stem end at least one insulating umbrella mounted on the stem, in which the umbrellas are formed by first arranging an insulating mould umbrella on the stem to define a cavity between the mold umbrella and the stem and then filling the cavity at least partly with a hardenable insulating synthetic material.  When hardened, the material completes the formation of the umbrella with the mould, and also secures the umbrella to the stem.  Arrange-ments for increasing the surface leakage path are described, using an annular sleeve which can be inserted into the mould umbrella, or by using a cover which can be placed on the mould umbrella.  A sealing arrangement between the inner part of the mould umbrella and the stem to prevent loss of the harden-able synthetic material is also described.  In the method for making the insulators, a variety of synthetic materials may be employed, both for the filling material and for the mould umbrellas themselves, such as cycloali-phatic epoxy resins, silicone rubber, the mould umbrellas may also be of butyl rubber, fluorosilicone or polysulfide.

Abstract: BUBBLE DOMAIN CIRCUIT ORGANIZATION            Abstract of the Disclosure An on-chip bubble domain circuit organization.  One or more storage registers are connected to a propagation path whereby data in the form of magnetic bubble domains (bubbles) may be transferred into and out of the storage registers.  The propagation path includes a generator for producing the initial bubbles which are expanded into any desired number of new bubbles by a unique multiple output replicator.  A unique input decoder is utilized to determine to which storage reg-ister the bubbles from the replicator will be directed along the propagation path.  Those bubbles not selected may be annihilated.         An output decoder utilizing essentially the same decoding scheme as the input decoder, selectively receives bubbles from the storage register.  A transfer and replicate switch is utilized between the storage register and output decoder to selectively transfer bubbles to the output decoder.          The output decoder may collapse all of the bubbles from certain storage registers so that only the information from the selected storage register reaches the detector.  The detectors in turn produce the chip output signal.  External control electronics are utilized to control the selective operation of the various devices utilized in the propagation path.

Abstract: ABSTRACT OF THE DISCLOSURE         In an electrostatographic copier in which an imaging surface is corona charged by high voltage biased electrodes, particularly those in which corona wires overly a reusable photoreceptor, protection of the imaging surface from arcing from the corona electrodes, particularly in the case of corona wire breakage, is provided by automatic rapid interruption of the high voltage to the electrodes, by electrically detecting sudden change in the current to the electrode.  This detection is accomplished at low voltage levels, yet with appropriate circuitry the high voltage can be rapidly switched off or shorted to ground.  Simple, low cost exemplary circuits using high speed relays or gas discharge tubes controlled by current change detectors are disclosed.  Detection of sudden changes in the true electrode-to-imaging surface current, independent of changes in electrode-to-shield currents, is provided.
